The 1896 Rikuu earthquake was the biggest inland event occurred in Tohoku district and caused extensive building damage to Akita and Iwate prefectures. The authors have been done literature surveys on this earthquake and reported in the preceding papers clarifying distributions of building damage, cause of human casualties, local governmental responses and so on. In this paper, we focus to individual building damage and effects of regional features on building construction are discussed through the reconnaissance reports and related papers. Typical examples are also cited from photos and illustrations appeared on those documents and discussed.

The aim of this study is to clarify the structural characteristics around eaves on the buildings and their transition built by the fifth Oguro, Mokuemon, a master carpenter in Echigo. In conclusion, this study clarified that the “Segai bracket structure” are generally used only for the temple main buildings and houses. In the temple main buildings with the “Segai bracket structure”, the construction style of eaves and bracket generally differ between front and other sides. The transition that the “Segai bracket structure” expanded from rear and lateral to all sides was established with the Kichijoji temple main building (1832).

街の雰囲気のちがいとは何か。雰囲気を感じているのは人であり，見ている対象は街である。街の雰囲気のちがいとは何かという探求から始めた本研究は，場の固有性の論理を解明することを主な目的とする。街の雰囲気は，場の個性や特徴といったその場に固有な性質，すなわち場の固有性のことと定義できるように思う。 また別の言い方をすれば「景観」という言葉を当てはめられるとも考えられる。今回は2020年度に行った玉城邸の実測調査の内容を報告する。

Thus far, the quality of cedar wooden-shingle boards, a traditional Japanese roofing material, has only been visually evaluated, because quantitative criteria have not been established. The purpose of this research is to investigate a criterion to determine the quality of wooden-shingle boards based on their physical properties. A visual evaluation by experts was conducted to assess the quality, as well as visual and physical attributes of board samples. The relationship between these results and the physical properties (color, bending strength, and annual rings) was analyzed through multiple regression analysis. The attributes of “good product” and “suitability” correlated well with the physical properties of the color and annual rings. A small contribution from the bending coefficients was also observed for the attribute of “good product.” These results indicate that the quality of wooden-shingle boards can now be estimated quantitatively from the colorimetric value and the number of annual rings.

Cedar wooden-shingle boards used as the Japanese traditional roofing material are handmade by craftsmen, and there is a need for technology that stabilizes its product performance. Therefore, the purpose of this study is to establish a method for quantitatively selecting cedar wooden-shingle boards by non-destructive methods based on color of the board, as done by craftsmen. Hence, in this report, a relationship was analyzed to evaluate the boards’ strength from colorimetric values by using a “transverse direction 3-point bending test”. As a result of multiple regression analysis, CIE L*, a*, and b* were adopted as coefficients, and confirmed that the maximum bending stress of the test piece can be predicted with a high correlation based only on the color. Furthermore, data from different types of color measurement instruments were compared and similar findings were observed.

 Gangi-Dôri is a type of alley for pedestrians, which is created as a measure to cope with deep snow. The Gangi which forms part of resident’s homes is made an integral part of the town street so as to form arcade-type sidewalk. In the Edo era, Gangi-Dôri was constructed for the purpose of securing function of passages in the heavy snowfall areas.

 This is a research of private use of spaces under eaves in front of houses （Machiya） and decline of the Gangi-Dori between the Meigi era and the Taisho era in Yamagata Prefecture by focusing on collection of paintings and old pictures. This time, the analysis was limited by the small amount of historical material, and it is necessary to collect and analyze some more historical materials in the future.

 Ujiie cleared the peak period of construction and development of Gangi-Dôri was between the end of the Meiji era and the early Taisho era. On the other hand, as a result of this research, Gangi-Dôri of the Yamagata prefecture was declined between the end of the Meiji era and the Taisho era. The decline of Gangi-Dori had two types.

 1)Eaves in front of houses（Machiya）were used privately by the owners because the space under the eaves were used for business. Furthermore, glass doors and lattices were fitted at the boundary between the eaves in front of houses (Machiya) and roads.

 2)Eaves in front of houses（Machiya）were covered for fire prevention after the big fire. This is a characteristic found in Yamagata prefecture.

 Magobisashi (small eaves) fixed on the eaves in front of houses (Machiya) was sometimes set out for snow protection and business.

The former second house of Higashifushimi Kunihide is one of the most important architectural landmarks representing Yokohama. It has been noted for its appearance. It was authorized as an Important Yokohama architectural Landmark at in 1993.
This report is a summary of the survey on the former second house of Higashifushimi Kunihide. The formerly second house of Higashifushimi Kunihide was built in 1937. It has a Japanese-style appearance although it is made of reinforced concrete. The interior is western style. And it has an associated warehouse.
